Two-ram. HINGE.

Specification of Letters Patent.

Patented Nov. 30, 1915.

Continuation of application Serial No. 474,167, filed January 25, 1909. This application filed February 4,

- 1911. Serial No. 608,632.

To all whom it may concern Be it known that I, ALFRED BFHIPOLITO,

a citizen of the United States, residing at.

Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Two-Part Hinge, of which the following is a specification.

This invention includes a two-part hinge shown in my application Serial No. 474,167, filed Jan. 25, 1909, and finally allowed Aug.

,5, 1910, of which application this is a conthis application and in which application I have shown a two-part hinge comprising leaves bent to form knuckles, said knuckles being interlocked so that the edge of one knuckle is inclosed within the other knuckle, the knuckle of one of said leaves being cut away to form a slot and orifice and the other having an extension in the form of an open hook projecting through said orifice so as to allow the leaves to be connected and separated when they are swung apart into approximately parallel planes.

An object of the invention is to provide a hinge of only two parts for hanging screens, windows, and the like; the same being. readily separable so that the screen or window may be readily hung in deeply recessed or other windows and as readily removed; said hinge being adapted for smooth and even hinge movement in the manner of an ordinary butt hinge.

Another object is to provide a hinge of the character stated which may be applied to hang a screen or other object at any part of an under side or surface, so that a screen may be hung to the top of the window-casing either at the margin of the windowframe or inwardly from such margin, so that the screen or other frame may be mounted where desired in the window-casing without interference of stops or molding.

posed solely of two parts, each of which is bent'in a form of very-great simplicity from a single piece of sheet metal, and the two being adapted for connection with each other without the use of a pin or pintle.

Other objects are lightness, strength, cheapnessyslmphclty, and ease of application and separation.

The invention includes the hinge and the separate parts thereof.

Theaccompanying drawings illustrate the invention applied to a window screen.

Figure 1 IS a fragmental, perspective, sectlonaldetail showing my hinge in use. Fig. 2- 1s a perspective of one member of the hinge. Fig. 3 is a perspective of the other member of the hinge. Fig. 4 is a fragmental cross-section through the window-casing and screen for the purposes of showing an edge view of the hinge with the screen closed and with the knuckle of the hinge outside of the face of the casing. Fig. 5 is a view analogous to Fig. 4 and showing the casing projecting beyond the knuckle and illus trating the operationof disconnecting the and viewed looking into the open knucklehooks. Fig. 8 is a view of the hook-faces of the two members that constitute the hinge. Fig.9 is'a view of the two parts of a hinge embodying the invention in another form. Fig. 10 is a section of said two parts connected together and in use, one part being fastened to the upper part of the casing and another'to the screen. Fig. 11 is a view of the hinge detached, the two parts being connected together. Fig. 12 is a view of two blanks from which the two parts shown in F 1gs. 9, 10 and 11, are struck up.

The strap 1 has the usual perforations 2 for the insertion of screws, and at one edge bent from the ends of *the knuckle without Another object is to provlde a hinge com being disconnected from the strap to form stops 5 and 6, said stops being bent inwardly to cross the axis of the knuckle.

The hinge formedby hooking the two hooks together practically consists of two fiat plates or straps, one end of each of which plates'is turnedin a single continuous segmental bend to extend over the ad-' jacent fiat face of its plate, the edge of each hook being contained within the other hook and one of said hooks being shorter than the other and said edges being withdrawable from and insertible into .the hook res ectively, by. slipping the edges past each ot er. In this manner the hinge is peculiarly adapted for attachment to the underside of a supporting surface at any place inside a cavity, so that the screen and the hmge, if desired,

may be wholly inside the cavity, as shown in Fig. 5, and may be shifted to any desired position inside the cavity, and may be disconnected from the support whenever swung out to nearly horizontal position,

whereupon by a slight inward movement of 5 the screen toward the interior of the house the screen may be readily moved, and upon reverse movement can be as readily replaced, but cannot be removed when in a vertical position.

The stra 7 has ornamental edges 8 which may be 0 any desired configuration, and the strap is provided with one or more perforations 9 for the insertion of permanent screws, and a slot 10 for the insertion of an adjusting screw. A rolled continuous 0 en knuckle 11 in the form of a curved hoo is integral with the strap 7 and has the openand between the stops.

ing 12 between its edge and the strap; said knuckle 11 being of smaller diameter than the knuckle 3 and of a length which will readily insert and fit between the stops 5 v and 6, so that the two members of the hinge,

may be connected by placing one reverse side up relative to the other in longitudinal alinement and over-lapping so as to hook the knuckle 11 into the opening 4, thereby bringing the knuckle 3 into the opening 12 Then when the members are swung at right angles to each other, as in Figs. 1 and 1:, it is obvious that they cannot be unhooked and se arated.

By hooking the knuckles toget er in thisway, I do away with the necessity of a pin'v holes 2 against the upper 'part 13 of the window-casing, and will then insert the screen-frame 14 into the window-frame and bring it against stops 5, 6, and then by striking the screen-frame with a hammer to drive. it forcibly against the stops 5, 6, he may make imprints. on the frame so that when he removes the screen hevwill be able to the vertical edges of the screen-frame.

to properly position the straps 7 relative He will then fasten the straps 7 by screws 15 inserted through the slots 10; and tight io ened sufliciently to prevent the straps irons;v sli pin too readily. Then the screen-immigwi 1 be ung in position, and may be moved relative to the straps so as to fit inside the window-casing. T en he will unhook the screen-frame and tighten the screws 15 and inside other screws 16 through the holes9 to hold the stra s in fixed position.

It is obvious t at when-a screen or window has been hung in this way the same may be readily removed for cleaning the window or for. storage',as in winter,by swingi the frame outwardly to a horizontal position and then unhooking the'knuckles of the hinges; and that'the screen or window may be readily replaced by the'reverse operation. 4 The end of the insertion-hook 11 may be tapered, as shown in Figs. 7 and 8, so that it will more readily enter between the stops of the other member.

In Fig. 3 the slits 17 are of less length than the bend of the hook 350 that the ex posed portion of the member 1 will appear uninterrupted. v

In-Fig. 5 'I have shown the stra 1 ap plied tothe lower face of a projecting casing, whereas in Figs. 1, 4, 10.'the knuckles are flush with the casing. It is obvious the upper straps may beset where required in an case;

inclusive, the material of. the strap 1 between the slits 17 is removed.

It is understood that .the edges of the hooks which are interlocked may be variously formed and that they need not-extend unbrokenly or in straight lines from stop to I stop; it being necessary only that requisite portions of the knuckles, which I have termed their edges, be inclosed one within the other. When it is desired to lock the knuckles permanently together in their hooked sition the mechanic may, after said hooks being interlocked with the edge of each inclosed within the other, the hook of one of said lates being slitted andbent at each end to cm stops.
